IMPROVEMENT IN TRANSMITTING TIME-MOVEMENTS T0 DISTANT DIALS.

Specification fonning part of Letters Patent No. 196,404, dated October 23, 1877; application filed August 28, 1877.

To all whom it may concern:

Be it known that I, HERMANN J. WENZEL, of San Francisco, in the State of California, have im'ented an Improvement in Clock- Movements, of which the following is a specification:

In Letters Patent No. 140,661 a device is shown and described whereby several timepieces are actuated synchronously by means of air conveyed through tubes from a central motor or time-piece. The present invention relates to the mechanism of the distant timepiece.

The air acts upon an inverted cup in a ves; sel containing mercury, glycerine, or other liquid, and causes said cup to rise and fall, and gives motion to a lever that acts in turn upon two levers provided with pawls and stops, that give rotation to one of the wheels air from said cup, and the action of the air al-' ternately forced in and exhausted from the cup gives an up-and-down motion to said cup, and also to the lever c, to which it is connected by the link 0. This lever is provided with a counterpoise at h, to balance the weight of the cup b, and lessen the amount of air required to move it.

The lever c is upon the shaft (1, and upon said shaft there is a bent lever, i, connected to a second bent lever, l, by a pin and slot at m. There are pawls n o and stop-pins t it upon the levers i l, respectively, and said pawls engage with teeth upon the wheel '0, that is one of the wheels of the clock-movement.

As the cup I) rises, the lever i is moved by the lever c, and the pawl 12 turns the wheel o half the distance between two teeth. The wheel is now stopped by the pin t coming against said wheel, and prevents it being moved too far. During this time the lever I has been moved, the pawl o drawn back, and the stop it moved away from the wheel 12.

When the cup b descends, the reverse operation takes place, the pawl 0 turns the wheel until arrested by the stopu, and the pawl n is drawn back and the stop l moved away from the wheel, so as to be ready to act when the cup b rises again.

By this arrangement the parts move with but little friction, and the clock-movement is operated with the utmost regularity. I claim as my invention- The levers c i l, pawls n 0, stops t u, and wheel 22, in combination with the vessels 1) c and air-tube a, substantially as and for the purpose specified.

Signed by me this 17th day of August, A. D. 1877.
